LIFSCI 7B XL - Animation: Carbon Cycle
Questions and Answers Rated A+
How does carbon enter the atmosphere during the carbon cycle?
✔✔ Carbon enters the atmosphere as carbon dioxide (CO₂) through processes like respiration,
combustion of fossil fuels, and volcanic activity.
What role do plants play in the carbon cycle?
✔✔ Plants absorb CO₂ from the atmosphere during photosynthesis, converting it into glucose
and storing it as organic carbon in their biomass.
How is carbon transferred from living organisms back into the environment?
✔✔ Decomposition of dead organisms by decomposers releases carbon back into the soil and
atmosphere in the form of carbon dioxide and methane.
What is the significance of the ocean in the carbon cycle?
✔✔ The ocean acts as a carbon sink, absorbing large amounts of CO₂ from the atmosphere,
where it can be stored in dissolved forms or used by marine organisms for shell-building.

, How do human activities disrupt the natural carbon cycle?
✔✔ Human activities like deforestation and the burning of fossil fuels increase the concentration
of CO₂ in the atmosphere, leading to global warming and climate change.
What is the role of sedimentation in the carbon cycle?
✔✔ Carbon can be stored long-term in sediments, such as in the form of limestone and fossil
fuels, which are eventually buried and locked away from the atmosphere.
How do animals contribute to the carbon cycle?
✔✔ Animals contribute to the cycle by releasing CO₂ through respiration and, after death,
through decomposition, which returns carbon to the environment.
How does carbon sequestration in forests affect the carbon cycle?
✔✔ Forests sequester carbon by storing it in trees and soils, reducing the amount of CO₂ in the
atmosphere and mitigating the impacts of climate change.
Why is the carbon cycle considered a crucial part of the Earth's ecosystem?
✔✔ The carbon cycle regulates the amount of carbon dioxide in the atmosphere, influencing
climate, supporting plant growth, and maintaining the balance of Earth's ecosystems.
